I was a little confused as well. You said that you started out with the 2.0ghz model...and then ended up with a 2.2ghz model with better graphics hardware. Did you pay extra for the 2.2ghz model...or did Apple offer it to you at no extra charge?

Thanks,

I opted to pay for the upgrade because I felt I needed better graphics processing power, it wasn't offered. I tested various things on the replacement 2.0GHz model and wasn't satisfied with the outcomes.

As you said, it was nice of them to let me exchange things no questions asked
